1. Density

2. Density Density The amount of matter in a given amount of space
The formula for density
D= mass divided by volume
D=M/V M D V

3. Importance of density Density is a physical property
Every substance has a specific density at a given temperature
The density is constant regardless of the amount of the substance
A glass of water has the same density as a swimming pool filled with water.

4. Density and Gravity
When placed together, substances will arrange themselves based upon density
Substances with higher densities on the bottom
Substances with lower densities on the top
Why HDL is better than LDL

5. The density of water Water is unique substance
Water has a density of 1g/ml
Solid water has a density of .9167g/ml
That is why ice floats
The density of sea water is 1.025g/ml

6. How things float
The percent of an object that is above water is base upon its density
A block with a density of .6g/ml will have 40% of the block above the water line.
Remember the density of water is 1g/ml
1g/ml-.6gml = .4

7. Why icebergs are so dangerous

8. Density column The liquids do not mix together
The liquids settle out based upon their densities

9. Density and the Earth

10. Density and Weather

11. Density Summary Density – the amount of matter in a given space
Formula – D= M/V
Substances will layer based upon densities
The amount floating above the surface is base upon the relative densities of two substances
